In late June we showed that ASX short sellers never made a macro bet against oil — they made a company-specific bet against Beach Energy while waving Woodside and Santos through. In July we showed the positioning rotating ahead of the news: Beach bears taking profits, Karoon bears reloading, Santos tripling off a record low.
Six weeks on, the rotation has finished, and it went somewhere nobody watching the June tape would have guessed.
Short sellers have unwound their positions across almost the entire ASX energy complex — and the single exception is Woodside, the name they had ignored all year.
What this data is, and when it is from — ASIC publishes aggregated net short positions on a T+4 basis. Figures below run to 17 August 2026 and are compared against 6 July 2026 — the reference date used in our previous piece, and the eve of the last escalation. All figures are net short positions as a percentage of issued capital.
The rotation, in one table
| Ticker | Company | 6 Jul | 17 Aug | Move | Read |
|---|---|---|---|---|---|
| WDS | Woodside Energy | 2.50% | 3.32% | +0.82pp | The only build |
| BPT | Beach Energy | 8.60% | 8.53% | −0.07pp | Held, not added to |
| WHC | Whitehaven Coal | 1.55% | 1.28% | −0.27pp | Trimmed |
| STO | Santos | 0.65% | 0.37% | −0.28pp | Back toward the floor |
| KAR | Karoon Energy | 4.66% | 4.33% | −0.33pp | The reload, unwound |
| WOR | Worley | 2.21% | 1.77% | −0.43pp | Trimmed |
| VEA | Viva Energy | 0.89% | 0.30% | −0.60pp | Nearly gone |
| ORG | Origin Energy | 1.71% | 1.00% | −0.70pp | Largest reduction |
Seven of eight names de-shorted. One did not. That is not a complex-wide risk adjustment — a general de-risking would have taken Woodside down with everything else.
Why the Woodside build is the interesting number
Go back through the series and the striking thing about Woodside is how little short sellers have ever cared about it. Across the past twelve months the position peaked at just 4.20% (17 February) and spent most of the period between 2% and 3%. In July we described it as "still a non-event", and that was the correct read at the time.
At 3.32% it is still not a large position in absolute terms — Beach carries more than two and a half times as much. But it is the direction that matters. Every other bear in the sector was reducing, and this one was adding.
The move is also proportionally significant: +0.82pp on a 2.50% base is a 33% increase in the size of the position in six weeks.
The Karoon reload didn't work out
The most direct test of our July piece is Karoon. We flagged it as "the reload" — short interest climbing from 3.18% to 4.66% while the ceasefire wobbled, positioning built for a second leg of escalation.
Karoon short interest is now 4.33%, down 0.33pp. The reload was unwound rather than pressed.
For context on how far this position has already travelled: Karoon's twelve-month peak was 9.91% on 27 February. Today's 4.33% is less than half that. Whatever the bear case was at the February peak, most of it has been closed out.
Beach: the one position nobody is giving up
Beach Energy remains the anchor of the sector's short interest at 8.53%, essentially unchanged from 8.60% six weeks earlier — and off a twelve-month peak of 9.88% set on 23 June.
This is worth sitting with. Through an escalation, a ceasefire, a de-escalation and a complex-wide unwind, the Beach position has barely moved. That is the signature of a structural short rather than a tactical one. Tactical positions get taken off when the catalyst passes. This one has not.
Santos and Viva: back to nothing
Two names have effectively exited the board.
Santos is at 0.37%, down from 0.65% and against a twelve-month peak of 0.86%. In July we noted the position had "tripled off the floor" — it has now gone most of the way back to it. On a company of Santos's size, 0.37% is close to noise.
Viva Energy is more dramatic still: 0.30%, down from 0.89% six weeks ago and from a twelve-month peak of 5.75% last August. The refiner short is gone — down roughly 95% from its peak.
What this pattern is, and what it isn't
The honest reading is narrower than the headline suggests.
What the data supports: short sellers reduced exposure across seven of eight ASX energy names between early July and mid-August, while increasing a position in Woodside by a third. That is a rotation, and rotations are usually deliberate.
What the data does not support: any specific thesis about why. ASIC's aggregate contains no reasoning. A Woodside build is consistent with a bearish view on the company, with a hedge against a long position elsewhere in the sector, with an arbitrage against a corporate action, or with an index-related trade. These are indistinguishable in this dataset.
And one structural caveat, the same one that applies to every piece we write on this data: T+4 reporting means the tape you are reading was set roughly four days before publication. Positioning is a lagging record, not a live feed. The value is in the direction of travel across weeks, not in any single print.
What to watch
- Whether the Woodside build continues past its February peak of 4.20%. That is the level at which it stops being an outlier and becomes the sector's second real short.
- Whether Beach ever breaks. At 8.53% it has been remarkably stable through everything the last two months threw at it. A decisive move in either direction would be the sector's most informative signal.
- Whether Santos and Viva stay at the floor. Both were higher earlier in the year. Positions that return to near-zero sometimes stay there for years — and sometimes come straight back.
